If you have Python, here's an alternative:

Code:
#!/usr/bin/python
data = open("data.txt").readlines() #get data into array
data = [i.strip() for i in data]  #strip newlines for each element
unique = set(data) #get unique elements
for element in unique:
 	print "%s has %i counts." % ( element, data.count(i) )

output:
Code:
abc has 4 counts.
ghi has 4 counts.
def has 1 counts.

TIFFWriteRawstrip(3TIFF)												  TIFFWriteRawstrip(3TIFF)

NAME
TIFFWriteRawStrip - write a strip of raw data to an open TIFF file SYNOPSIS
#include <tiffio.h> tsize_t TIFFWriteRawStrip(TIFF *tif, tstrip_t strip, tdata_t buf, tsize_t size) DESCRIPTION
Append size bytes of raw data to the specified strip. NOTES
The strip number must be valid according to the current settings of the ImageLength and RowsPerStrip tags. An image may be dynamically grown by increasing the value of ImageLength prior to each call to TIFFWriteRawStrip. RETURN VALUES
-1 is returned if an error occurred. Otherwise, the value of size is returned. DIAGNOSTICS
All error messages are directed to the TIFFError(3TIFF) routine. %s: File not open for writing. The file was opened for reading, not writing. Can not write scanlines to a tiled image. The image is assumed to be organized in tiles because the TileWidth and TileLength tags have been set with TIFFSetField(3TIFF). %s: Must set "ImageWidth" before writing data. The image's width has not be set before the first write. See TIFFSetField(3TIFF) for information on how to do this. %s: Must set "PlanarConfiguration" before writing data. The organization of data has not be defined before the first write. See TIFFSet- Field(3TIFF) for information on how to do this. %s: No space for strip arrays". There was not enough space for the arrays that hold strip offsets and byte counts. %s: Strip %d out of range, max %d. The specified strip is not a valid strip according to the currently specified image dimensions. SEE ALSO
